Webshop Laravel Package

Technical Evaluation

• Architecture fit: Reasonable only for Laravel 11 applications that need a Mollie payment integration. 4.0.0 is a platform-forcing major release: Laravel 11 only and Mollie API 3.0. For services on Laravel 10 or earlier, it is not a drop-in update; it requires a framework upgrade first. For Laravel 11, it can reduce custom Mollie client code and centralize configuration, payment creation, webhook handling, and response mapping.
• Integration feasibility: Feasible for a Laravel 11 codebase with PHP 8.2+ and an existing Mollie account. Composer install, config publishing, and service-provider wiring are standard. The real effort is validating Mollie API 3.0 behavior across payment creation, redirects, webhooks, refunds, and recurring/subscription flows if used.
• Technical risk: High upgrade risk because both release constraints are breaking: Laravel 11-only creates framework coupling, and Mollie API 3.0 may introduce request/response, authentication, webhook, or model changes. Narrow compatibility increases risk in multi-version Laravel estates.
• Key questions: Is the product already on Laravel 11? What PHP version is supported? Which Mollie flows are in scope: one-off payments, refunds, subscriptions, chargebacks? Are existing webhook handlers and idempotency patterns compatible with Mollie API 3.0? Does the package expose every Mollie feature the product needs? What is the maintainer’s cadence for future Laravel releases? Is direct use of the Mollie SDK a viable fallback?

Integration Approach

• Stack fit: Good fit for a Laravel 11 monolith or service using Composer. Poor fit for older Laravel versions, older PHP, multi-version Laravel estates, or non-Laravel services. Keep payment logic behind an internal service boundary if multiple apps share Mollie flows.
• Migration path: Upgrade the host application to Laravel 11 first, then adopt package 4.0.0 in a branch. Reconfigure Mollie credentials for API 3.0, run sandbox tests for payment creation, redirects, webhooks, refunds, and failure states. Treat this as a major migration if coming from an older package major.
• Compatibility: Laravel 11 only is the controlling constraint. Confirm PHP and dependency compatibility, including HTTP client, event, and webhook libraries. Validate Mollie API 3.0 against account settings, webhook URLs, signing/verification if used, and any subscription or refund endpoints.
• Sequencing: 1) inventory Laravel/PHP versions and payment flows; 2) upgrade Laravel 11 in staging; 3) install package 4.0.0; 4) run sandbox integration tests; 5) test webhooks and reconciliation; 6) canary low-risk production payments; 7) complete rollout with monitoring and rollback/pinning plan.

Operational Impact

• Maintenance: Expect annual upgrade pressure from Laravel’s release cadence. A Laravel-11-only major means Laravel 12 support may require another major package release. TPM should budget recurring upgrade windows and track both package and Mollie API lifecycle.
• Support: Maintainer responsiveness matters because the major version narrows compatibility. Confirm issue-response expectations, security policy, and whether previous package majors continue to support older Laravel versions.
• Scaling: Payment throughput depends mainly on Mollie and the application’s webhook processing. Use queued webhook handling, idempotency keys, retries, and reconciliation jobs. Avoid synchronous payment confirmation in user-facing requests.
• Failure modes: Laravel/package version mismatch; Mollie API 3.0 breaking behavior; webhook delivery failures or duplicate events; payment state divergence; credential or configuration errors; unhandled refund/subscription changes. Add dead-letter queues, webhook-failure alerting, and daily reconciliation.
• Ramp-up: Low for Laravel developers familiar with Composer and service providers; moderate for Mollie API 3.0 payment lifecycle and webhook semantics. Provide runbooks for sandbox testing, webhook replay, refunds, and rollback or version pinning.
